"To me it seems that the warm blooded dinosaurs replaced advanced mammal ancestors that were warm blooded, also"

Robert T. Bakker's quote suggests that the warm-blooded dinosaurs that existed during the Mesozoic Era changed the sophisticated mammal forefathers that were also warm-blooded. This recommends that the warm-blooded dinosaurs were more effective than the mammal forefathers in terms of their ability to survive and flourish in the Mesozoic Era. This could be due to the reality that the warm-blooded dinosaurs had a more effective metabolism, allowing them to be more active and much better adapted to their environment. Furthermore, the warm-blooded dinosaurs may have had a more varied series of habitats, allowing them to expand and occupy more areas than the mammal forefathers. This could have provided an advantage in regards to competitors for resources and survival. Ultimately, this quote suggests that the warm-blooded dinosaurs were more successful than the mammal forefathers in the Mesozoic Era, likely due to their more efficient metabolism and diverse series of environments.
